[Gnuplot-info] Problem with 3d plot and coloring

[Idar B. <ida...@gm...>]

Hi

I am trying to plot a cube with only dots, and i want to color the
dots acourding to some numbers i calculate. Is this possible?
Its fairly easy to plot 3d but the color comes as a function on the z value.

I do not subscribe to this list so please reply to me too.

Yes.  (Re-)read the documentation sections about pm3d and splot to find 
out how.

... only if you don't say otherwise.

... and failed to find option 'palette'.  And the possibility to specify 
4 columns of data, too.

I think you were looking for some variation of

	splot 'out.dat' using 2:1:3:4 with points palette
